Cedrelaspecies are attacked by the tip mothHypsipyla robustawhen grafted on to red cedarToona ciliata

Publikováno v: Australian Forestry. 61:45-47

Summary Australian Red Cedar (Toona ciliata) grown in plantation on the NSW mid-north coast is severely attacked by the shoot borer Hypsipyla robusta. Exotic species of Cedrela (C. odorata C, de Candolle and C. fissilis Vel.) grown in the same area a

Efflux of hepatic ascorbate: a potential contributor to the maintenance of plasma vitamin C

Autor: J M, Upston, A, Karjalainen, F L, Bygrave, R, Stocker

Publikováno v: The Biochemical journal. 342

Ascorbate (AH, the reduced form of vitamin C) is an important radical scavenger and antioxidant in human plasma; the resulting ascorbyl radical can disproportionate to AH and dehydroascorbic acid (DHA). Here we address potential maintenance mechanism

Hormone-induced bile flow and hepatobiliary calcium fluxes are attenuated in the perfused liver of rats made cholestatic with ethynylestradiol in vivo and with phalloidin in vitro

Autor: Y, Hamada, A, Karjalainen, F L, Bygrave

Publikováno v: Hepatology (Baltimore, Md.). 21(5)

The actions of vasopressin and glucagon, administered alone or together, were assessed on bile flow in perfused livers from rats made cholestatic by the injection of ethynylestradiol and from those allowed to recover from such treatment. Concomitant

Evidence that stimulation of plasma-membrane Ca2+ inflow is an early action of glucagon and dibutyryl cyclic AMP in rat hepatocytes

Autor: Alessandra Gamberucci, F L Bygrave, Rosella Fulceri, Angiolo Benedetti

Publikováno v: The Biochemical journal. 292

The ability of glucagon (1 nM) and of dibutyryl cyclic AMP (50 microM) to increase cytosolic free Ca2+ concentration ([Ca2+]i) in Fura-loaded rat hepatocytes was examined in a system wherein Ca2+ inflow was induced by the re-admission of excess Ca2+

The influx of Ca2+ induced by the administration of glucagon and Ca2+-mobilizing agents to the perfused rat liver could involve at least two separate pathways

Autor: F L Bygrave, J G Altin

Publikováno v: Biochemical Journal. 242:43-50

The Ca2+-mobilizing actions of ADP, ATP and epidermal growth factor (EGF) and their interaction with glucagon were studied in a perfused liver system incorporating a Ca2+-selective electrode. ADP (1-100 microM), ATP (1-100 microM) and EGF (10-50 nM)

Synergistic stimulation of Ca+ uptake by glucagon and Ca2+-mobilizing hormones in the perfused rat liver. A role for mitochondria in long-term Ca2+ homoeostasis

Autor: F L Bygrave, J G Altin

Publikováno v: Biochemical Journal. 238:653-661

A perfused liver system incorporating a Ca2+-sensitive electrode was used to study the long-term effects of glucagon and cyclic AMP on the mobilization of Ca2+ induced by phenylephrine, vasopressin and angiotensin. At 1.3 mM extracellular Ca2+ the co

Properties of energy-dependent calcium transport by rat liver microsomal fraction as revealed by initial-rate measurements

Autor: F L Bygrave

Publikováno v: Biochemical Journal. 170:87-91

Measurements of the initial rate of Ca2+ transport by rat liver microsomal preparations reveal the existence of two phases of transport activity. The first, a phase of rapid transport, is complete by 3-5 min, at which time the second (slower) phase b

Glucagon stimulation of ruthenium red-insensitive calcium ion transport in developing rat liver

Autor: F L Bygrave, P H Reinhart

Publikováno v: Biochemical Journal. 194:541-549

The maturation of glucagon-stimulated Ruthenium Red-insensitive Ca2+-transport activity was determined in livers of rats ranging in age from 5 days preterm to 10 weeks of adult life. Previous indications are that this activity is confined to vesicles

The Ca2+-mobilizing actions of vasopressin and angiotensin differ from those of the α-adrenergic agonist phenylephrine in the perfused rat liver

Autor: F L Bygrave, J G Altin

Publikováno v: Biochemical Journal. 232:911-917

A Ca2+-sensitive electrode was used to study net Ca2+-flux changes induced by the administration of phenylephrine, vasopressin and angiotensin to the perfused rat liver. The studies reveal that, although the Ca2+ responses induced by vasopressin and
